Slide 44 is provided with a raclr 46 which 'b .is in mesh with a gearlsegmeirt 147 secured to a shaft 48 having rocking movement in a bearing 49. To rock-'shaft 48 isisec'ured a P forward end. of pliini of upper and lower plates 57 and two inwar ly .upper plate 57 1s provided 58. The lower edges 'of theldownwardly extending folders are angle of about 20 indicated at 60. vided with surfaces 61 which curve downwardly toward the inner sides of the downwardly extending folders 59. The lower plate '57 is rovided with two holders 62 `which exten vertically upward in line with said downwardly extending 'folders and have their u V.per edges angle o about 20 from said lower plate,' as

indicated at 63. The lower plate 57 is provided with surfaces 64 which curve'u ward toward the inner sides of the upwar ly extending folders 62. z f When the plunger 54 4reachesthe end of its travel in the direction indicated .by the arrowlin Fig. -1, the articles. 56 resting on the plunger will -fall to" the support 65.

Forward movement of 'the plunger will then force one of the articles 56 against the wrapper 39 andthe article and` wrapper being' then forced between 'the upper and .lower plates .57 and the inwardly 'extending side projections 58, cause the wrapper and the {iaps a. thereof to be folded upon the article in'the manner shown in Fig. 2.' At the end of forward movement of plun er54, the article and wrapper will bel move to the position shown in Fig, 12, duringV which the upperflaps b of the wrapper will take against the inclined edges 60 ofthe downwardly extending folders said upper flaps to be turned down and the wrapper rounded corners c of in Fig. 4. of plunger 54', the

moving rearwardly, and -at the end of the llatters movement, the plunger 25 pivoted thereon will be raised from .the position shown in Fig. 12 ,to-the position shownI in ,Fig. 1'. Then, vvhile lunger 54 continues its return movement, t e ivoted plunger 25 will' be moving forwardl in the reverse direction,

e moved forward; vthereby causing, the lower flaps d of the wrapper to` be moved 59, and against the' j rounded ends 66 of thecurved surfaces-61,I

causing to be 'forced against 'the' the article 56 as 'shown' During partial returnmovement plunger 19 will also be,

inclined downward at an from the upper plate as The upper plate 57 is proinclined upward at anA movement ico causingthe article and wrapper to beneath paste coated wheels 67 which are revolvingv inthe same vdirection as the flaps are moving, whereby paste is applied tot lower flaps, as lshown at'c in Flg. 4.

Plonger 54 will then have reached the end of its return m'ovementLand while it is beginning another forward movement, the pivoted plunger 25, will be completing its forward travel, causing the article and wrapper t;

be'moved forward to the position shown in Fig. 1'5. During this movement of the' article and wrapper, the paste coated lower fiaps lof the wrapper take against. the inclined edges 63 of the'upward] extending folders 62, and against 1,ciagrary be turnedfup against the folded llnps'bv find" causing the wrapper to be forced agnmst stile` rounded corners f of the article, as

, Movement of an article and wrap er into they receiving chamber is chec ed by means of a vertical wall 115 having an intern ally screw-threaded extension 116 which is engaged by'a screw. 117. By rotation of the l screw 117 the Wall 115 can be moved to'- flding channel( ward -the wrapper folding. channel, thereby reduci the'sizeof the receiving chamber 20 5 for t e purpose of receiving shorter arti-y cles thatmay b e passed throug the wrapper Shorter articles 56 placed in the magazine require shorter wrappers 39, which render it necessary -for the su ports 40 to be raised in order 4that the mid l'e of a wrapper shall beinline with the wrapper folding channel. To eil'ect adjustment of the supports 40, a clamping screw .118 passing through a slot 119 in each support and into a wall of the chute 41 is loosened, ,and the supports 40 movedlup and again clamped by means of the screws 118.y

Owing to the extra length of the wrapper folding channel constructed as described,

the stroke of plunger 54 is made sufficient to move an article and wrapper only part way# through the wrapper folding channel,.the pivoted plunger 25 beingprovided for conipleting the movement of said article and wrapper through the wrapper folding channel. l t will be seen that by timin the movements of lungers 25 and 54 wit reference to each ot er, asde'scribed, time consumed in part return travel of plunger 54 is gained by forward movement of an article 'and wrapper by means`of plunger 25, while time consumed in part return travel of plunger 25 is gained by forward movement of an article 'andwrapperby means of plunger 54.

Therefore extra lo articles 56 can be rapidly moved throu'g the wrapper folding channel.
